Any chance you could enable jit_dump_bitcode and manually try a failing query? That should dump. bc files in the data directory. That'd might allow debugging this outside the emulated environment. I don't see where the undef is originating from, but I think it might suggest that something lead to that code being considered unreachable. Andres -- Sent from my Android device with K-9 Mail.
